Windows 8.1 Preview

you are currently using Windows 8 you are aware that it obviously is a work in progress. While Windows 8 works fine on touch screens it can be clunky on non-touch screens. In addition if Microsoft has dreams of the corporate world adopting Windows 8 in the workplace further development and customization is required. Microsoft has obviously been working on some of these issues as the upcoming release of Windows 8.1 (or Windows Blue) proves. As with Windows 8 and Office 2013 Microsoft will be releasing a “preview” a few months before the final release on June 26.

It makes sense to look at what the Windows 8.1 Preview will bring to the table, and its requirements and changes, before you make a decision whether you should upgrade your system to the preview build right away.

For many users, it may be better to wait until the final version of Windows 8.1 gets released. While there is no definite date set for that yet, it is likely that Microsoft will make it available just a couple of months after the release of the preview version.

Requirements
The system requirements have not changed at all.

1 GHz or faster processor.

1 Gigabyte or 2 Gigabyte of RAM depending on whether you are using a 32-bit or 64-bit system.

16 Gigabyte or 20 Gigabyte of hard drive space again depending on whether you are using a 32-bit or 64-bit system.

Microsoft DirectX 9 graphics card.

Windows RT users need to have at least 10 Gigabyte of free storage on their device for the upgrade.
There is one main change though that users need to know about. You need to use a Microsoft account to sign in to PCs that run the preview build of Windows 8.1 There is no option to create a local account in the release, but Microsoft promises that it will be made available when the final version of Windows 8.1 gets released later this year.

Windows 8.1 Preview will be made available via Windows Store as a direct download and as a Preview ISO image. If you want to download it from Windows Store, you need to install an update first on the system that you get from the Windows 8.1 Preview download page. Next time you start the system after installing the update you receive a notification that you can get Windows 8.1 Preview for free from the store.

An Internet connection is needed to download the app from Store, but once it has been downloaded no Internet connection is required until the update has been successfully installed and the system rebooted.

You can alternatively download the Windows 8.1 Preview ISO from the download page and use it to install the operating system. You will need a product key that Microsoft makes available on the download page. It is likely that this is a generic key that all users who install the preview build share.

Unconfirmed
You will lose access to apps and programs that you have installed on Windows 8.1 Preview systems when you upgrade to the final RTM version of the operating system.

I may actually end up waiting if it is indeed true that all applications will need to be re-installed when moving from the preview release to the final RTM. I am still waiting on what is happening here before deciding what to do.
